2nd: vendilion clique vs delver of secrets in my deck do you think delver is even worth running? i like to hold mana open for counterspells early on anyway so delver might not even come down for 3-5 turns.

Geist by a mile. It's a threat that is almost impossible to get rid of. Plus, you've got enough removal to clear the way for it.

Delver by a mile. Again, it's a more durable threat that is easy for you to protect. You shouldn't be holding it, as there is very little turns 1-2 that you will ever need to counter. Anything the opponent can do on turn 1 (or even turn 2 if you're on the draw) can easily be undone by a Path to Exile or a Lightning Bolt.

Clique isn't really a threat. It's much more useful as hand disruption against combo or cards you simply do not have any answers for in the 75.
